One embodiment provides a slim acoustic transducer with a diaphragm including a hole that is substantially centered on a vertical axis of the diaphragm. The hole has a first horizontal width. A voice coil has a ring shape that is disposed at least partially within the hole and substantially centered on the vertical axis. The ring shape has an outer and inner horizontal width. The outer horizontal width is smaller than or equal to the first horizontal width of the hole. A column structure is disposed at least partially within the ring shape and substantially centered on the vertical axis. The column structure has a second horizontal width that is smaller than or equal to the inner horizontal width of the ring shape. The column structure includes an upper magnet, a middle plate disposed below the upper magnet and a lower magnet disposed below the middle plate.

Ultra slim transducer

One embodiment provides a waveguide for controlling sound directivity of high frequency sound waves generated by a speaker driver. The waveguide is positioned in front of the speaker driver. The waveguide comprises one or more ridge areas, one or more recess areas, and one or more smooth surfaces. Each smooth surface connects a ridge area to a recess area to create a smooth transition between the ridge area and the recess area without any seams or sharp transitions. The waveguide shapes propagation of the sound waves to provide a smooth off-axis frequency response for the sound waves.

Waveguide for smooth off-axis frequency response

One embodiment provides a speaker device comprising a first housing including a first top surface comprising a first opening, a first recessed mounting surface spaced below the first opening, and a first recessed sidewall extending upwardly from the first recessed mounting surface to the first opening to form a first waveguide. The speaker device further comprises a first upward-facing driver mounted into the first recessed mounting surface. The first waveguide shapes propagation of acoustic energy generated by the first upward-facing driver to project the acoustic energy out of the speaker device in an upwardly inclined direction.

Waveguide for a height channel in a speaker

One embodiment provides an omnidirectional loudspeaker comprising a first axisymmetric reflector, a second axisymmetric reflector, a sound source in the first axisymmetric reflector or the second axisymmetric reflector, and a horn including a straight section and a growth section extending from a distal end of the straight section. The growth section comprises one or more curves that are scaled with a radial coordinate and that expands sound waves generated by the sound source.

Three hundred and sixty degree horn for omnidirectional loudspeaker

One embodiment provides a sound apparatus comprising a plurality of driver units arranged linearly in an end-fire array, and for each driver unit, a corresponding digital filter for individual digital signal processing of signals received by the driver unit.

Beamforming array utilizing ring radiator loudspeakers and digital signal processing (DSP) optimization of a beamforming array

One embodiment provides an omnidirectional loudspeaker comprising a phase plug and an acoustic resonator within the phase plug. The acoustic resonator comprises acoustic damping material.
